Title: Equalizer
Inventor: MURAKAMI KEIJI
IPC: H04B7/005
Filed: 1989-12-04
Abstract: PURPOSE:To allow an equalizer to follow the variation of a transmission line and correspond also to high speed transmission by providing an operation part for executing the tap coefficient updating algorithm of the equalizer with plural operation parts having respectively different operating periods. CONSTITUTION:The equalizer includes two kinds of algorithm operation parts 100, 101 as tap coefficient updating algorithm parts. The operation part 100 for tap gain updating algorithm (A) estimates a transmission line in each symbol in a known sequence. The operation part 101 for tap gain updating algorithm (B) equalizes a data part by using a tap coefficient value obtained by the algorithm (A) as an initial value, but the data part may correct only a modelarate variation in Doppler frequency or the like. Thereby, a tap coefficient may be intermittently updated by estimating the changing speed of the variation. Thus, the equalizer can sufficiently follow a slow transmission line even by the intermittent operation.

Title: Optical switch
Inventor: SHINODA YOSHIHISA
IPC: H04B10/071
Filed: 1988-12-14
Abstract: PURPOSE:To omit a light source and its supply of power required at the terminal side by transmitting the beams of plural wavelengths via an optical fiber cable and reflecting different beams at the terminal side in accordance with the operation state. CONSTITUTION:The light transmitted via an optical fiber cable 14a is branched into two beams via a distributor 31 of a terminal switch 3 and supplied to 'Selfoc lenses(R)' 32a and 32b serving as the light focusing means. The light radiated from the lens 32a is supplied to a reflector 33a. A reflector 34a is set between the reflector 33a and the lens 32a in a state where the reflector 34a is freely attached and detached to cut off the optical path set between the reflector 33a and the lens 32a. As a result, the wavelength of the reflected light varies in accordance with the switch operating position. Thus the switch operating position can be decided by supervising the wavelength of the reflected light. In addition, the abnormality of a circuit is also decided from the combination of the reflected wavelengths.

Title: Acceleration sensor
Inventor: YOSHIDA TETSUO
IPC: G01P15/18
Filed: 1990-11-22
Abstract: PURPOSE:To detect acceleration in two orthogonal axes of X and Y by one sensor having a simple structure, by a method wherein a piezoelectric ceramic ring is subjected to a polarization processing by two terminals which connect band electrodes provided at positions dividing the outer peripheral surface of the ring equally by 4n, with one electrode left unconnected in between. CONSTITUTION:When a compressive force acts on the part of an output electrode 12 and a tensile force on the part of an output electrode 16, the directions of polarization for common earth electrodes of the output electrodes 12 and 16 are as indicated by arrows 20 of broken lines directed from the output electrodes to the earth electrodes likewise respectively, while the directions of the forces acting on the part of the output electrode 12 and on the part of the electrode 16 are reverse to each other as indicated by solid lines 21 and 22, respectively, and therefore voltages of reverse polarities are generated in the output electrode 12 and the output electrode 16. Accordingly, a differential output of these two output voltages turns to be proportional substantially with an applied acceleration. According to this constitution, an acceleration sensor for which angle adjustment at the time of setting is unnecessary is obtained by a simple structure using a piezoelectric ceramic ring of a single body.
